MELBOURNE - Aussie singer Natalie Imbruglia has revealed that she had a ’semi-nervous breakdown’ while working with ‘Coldplay’ frontman Chris Martin on her new album.

Imbruglia, 34, said that collaborating with Martin, 31, was difficult because of his directness.

“When I worked with Chris Martin he was very honest and brutal with me,” News.com.au quoted her as telling NME.

“He helped me with my tracklisting and we got rid of riff-raff. Sometimes we agreed, sometimes we disagreed.

“The hard bit is him saying which songs he doesn’t like, but it’s refreshing to have someone of that calibre with you.

“So yes - I had a semi-nervous breakdown,” she added.

Imbruglia’s new album ‘Come To Life’ is to be released on October 5. (ANI)
